Title (EN) METHOD FOR PREPARING POLYCARBONATE
(FR) PROCÉDÉ DE PRÉPARATION DE POLYCARBONATE
(KO) 폴리카보네이트 제조 방법
Abstract:
(EN) The present application relates to a method for preparing a polycarbonate, comprising the steps of: 1) adding, to a polycarbonate polymerization solution, an antioxidant and an anti-hydrolysis agent having an epoxy-fused aliphatic ring; and 2) removing a solvent from the polycarbonate polymerization solution by using steam. The present application can remove a solvent from a polycarbonate polymerization solution without deteriorating the physical properties of a polycarbonate.
(FR) La présente invention concerne un procédé de préparation d'un polycarbonate, comprenant les étapes consistant à : 1) ajouter, à une solution de polymérisation de polycarbonate, un antioxydant et un agent anti-hydrolyse ayant un cycle aliphatique fusionné par époxy; et 2) éliminer un solvant de la solution de polymérisation de polycarbonate à l'aide de vapeur. La présente invention peut éliminer un solvant d'une solution de polymérisation de polycarbonate sans détériorer les propriétés physiques d'un polycarbonate.
